Hello sudheer,
On LPC4357, there are no MIPI-CSI2 & CSI(camer sensor interface) interface for recieving camera data, so you can't connect OV5640 with MIPI-CSI2 interface to LPC4357 directly, so your application is spectial, about hardware connections, you can evaluate following advice:

Then you can get 1 Frame picture with JPG format through USB port in software!
Hope above advice can help you!
Best Regards,
